The Math.E property represents the base of natural logarithms, e, approximately 2.718.
Because E is a static property of Math, you always use it as Math.E, rather than as a property of a Math object you created (Math is not a constructor).
Math.EThe following function returns e:
function getNapier() {
return Math.E;
}
getNapier(); // 2.718281828459045
